A seven-piece simple stacking set with a unique shape, Beka's Stacking Blocks are made of sustainably-harvested maple in the United States. Each set contains three rectangular unit blocks with holes to fit the four round posts included. Multiple sets can be combined to build higher or more complex structures, and are fully compatible with Beka unit blocks for a wider array of building options. Wood is naturally finished with no coatings. Launch Date: 2009
